Ductwork cleaning in Coldharbour, done properly
Grease in a duct is hidden, which is exactly why it’s dangerous. Flames pulled in from the cooking line can ignite it, carrying a fire along the duct and into rooms far from the kitchen. Cleaning the duct takes that fuel away. Typical jobs include fat dripping from the ductwork and a grease test showing the duct is overdue, on vertical risers, access panels and multi-storey ducts.
Somewhere as small as Coldharbour, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Every one of them still needs its extract kept clear of grease.
For insurers and inspectors, the record counts. That is why every job is written up in a report with pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Common questions in Coldharbour
Do you do school kitchen extract cleaning in Coldharbour in the summer holidays?
Yes. Half-terms and the summer break are the natural time for school work. Food Standards Agency records list about 8 schools, colleges and universities with registered kitchens within about a mile and a half of Coldharbour. Tell us your holiday dates and we will book the visit for when the site is empty.
Can you work in Coldharbour outside opening hours?
Yes, we can come after you close and finish before you open. It means the site in Coldharbour keeps running as normal. Your opening times are the first thing we ask for.
How often should kitchen ducts be cleaned?
It depends mostly on daily cooking hours. Heavy use of 12 to 16 hours a day means at least every 3 months, while lighter use can go longer.
What accreditations do you have?
We hold CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
Do you offer maintenance contracts?
Yes. We run scheduled maintenance contracts, set at the interval the system needs. The report from each visit recommends the next date.
What’s TR19?
BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t law, but it’s the benchmark.
What shows that the ducts need a clean?
The date on the last certificate is the first thing to check. No record, or a passed date, means it’s due, and grease readings will confirm how urgent it is.
What do you do with what you remove?
We take it away when we go. While we work, it’s kept contained so the area stays clean.
Landlords, agents and facilities managers
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
Running several sites is easier with one contractor. We work across London and the South East, so visits at different addresses can be planned together and kept to a regular schedule.
Part by part
Vertical risers
Risers are cleaned through panels at different levels. Where it cannot be reached safely, the report says so.
Attenuators and discharge
Near the discharge, the air has cooled the most, which can mean heavier deposits. It’s tested and cleaned along with the rest.
Why act early in Coldharbour
Old grease in a duct for a kitchen in Coldharbour does not stay soft. Heat and age turn it into a thick, stubborn crust, so the later the clean, the bigger the job. Systems in rural buildings are often out of sight and out of mind.
Every site is different, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all make a difference.

Ductwork cleaning in Coldharbour: the local picture
The Food Standards Agency lists about 6 pubs and bars as registered food businesses within 1.5 miles or so of the middle of Coldharbour. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. In Coldharbour, food businesses are inspected by environmental health officers from Tonbridge and Malling council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Our report lists what was cleaned and when, which is useful to have ready. Coldharbour sits within the area of Kent Fire and Rescue Service. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract.
Ightham Mote, about 2.2 miles north, is one of the historic houses near Coldharbour; if you run event catering at a venue like that, cleans can be booked between functions. Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Tonbridge Cottage Hospital is the nearest hospital to Coldharbour, about 3.4 miles south. Term dates shape school work: for a school like St Margaret Clitherow Catholic Primary School, an extract clean fits neatly into a half-term or summer break.

What your team can do, and what needs us
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That is our job.
Looking after it afterwards
Simple habits between visits make a real difference. We recommend:
- Run the extract fan throughout service
- File each certificate and photo report in the maintenance log
- Leave a way through to the access panels
- Report any grease dripping from duct joints
Any section of duct we couldn’t reach is listed on the report, with the reason. We can fit access panels so those sections are cleaned next time.
Watch for warning signs between cleans: drips from the ductwork, stale smells or a noisy fan. Testing will show whether any section has reached 500 microns.
How it works
We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool first, and floors and nearby surfaces are sheeted. On site, it takes a shift or more, depending on the length of the runs and the number of access points. A few photos of the system help us make the most of a visit to a place like Coldharbour.
- First the duct route is traced and every access point noted.
- We measure grease thickness at set points before cleaning.
- We open the panels and scrape out the heaviest grease.
- Horizontal runs and risers are then degreased by the method that suits the deposit.
- Readings and photos are repeated and any section we couldn’t reach is recorded.
Preparing for the visit
- Make sure someone can let us in and lock up afterwards
- Find the previous report, if there is one
- Let us know how we reach the system, including roofs, risers and plant rooms
